Application filed August 5,1899.

To all whom it may concern:

Be it known that I, THOMAS ELLIOTT, a citizen of the United States,residing at Dallas, in the county of Polk and State of Oregon, haveinvented a new and useful Band-Cutter and Feeder, of which the followingis a specification.

This invention relates to band-cutters and feeders; and the objects inview are to provide means for effectively cutting the bands and properlydividing the sheaf and feed the upper portion considerably faster thanthe under part, to avoid choking of the cylinder and concave of thethresher, and thereby render the operation of the thresher much moreadvantageous and thorough, to afford convenient means for changing thespeed of the running parts, to accommodate different operations andunder varying conditions, and to supply adjustable features tofacilitate reduction of the longitudinal dimension of the device and itsarrangement over the end of the thresher, to which it'is attachedinfolded position. d

Other objects and advantages will appear in the snbjoined description,and the novel features will be set out in the claims, thepreferredembodiment of the invention being illustrated in theaccompanying drawings, wherein Figure l is a side elevation of theimproved band-cutter and feeder shown applied to the end of the thresherin operative position and also folded over in dotted lines to reduce thedevice to compact form when not in use. Fig. 2 is a top plan view of-theimproved band-cutter and feeder. Fig. 3 is a central longitudinalvertical section of the feeder and partfof the thresher as shownarranged in Fig. 1. r Fig. 4 is a detail perspective view of apart ofthe feeder. Fig. 5 is a detail view, in sectional elevation, of frictionmechanism for driving the lower draper and relative parts.

Similar numerals of reference are employed to indicate correspondingparts in the several views.

The numerals 1 and 2 designate contiguously-arranged sections hingedlyconnected by a transversely-extending pintle or-rod 3,. fitted incoinciding eat-s4 and 5, respectively projecting from the upperterminals of ver- Serial No 726,303- No model.)

tical straps 6 on the inner end of the section 1 and horizontal straps 7at the upper opposite edges of the section 2. At the outer end of thesection 1 is a transverse shaft 8. At the inner lower portion of. thesection 2 is a similar shaft 9, and on opposite extremities of the saidshafts are small sprocket-wheels 10, .to operatively receive the linksof chain belts 11 of a lower draper 12, having slats 13 ex tendingtransversely thereof at regular inter vals, provided withteeth 14,extending our-- wardly therefrom and curved rearward reversely to thedirection of the plane of movement of the said draper to feed the lowerpart'of said sheaf with a drag or slower than the upper portion. Theshafts 8 and 9 are located at opposite end portions of the bot toms 15and 16, respectively, of theseclions 1v and 2, the shaft 8 beinglongitudinally adjustable and having movably attached thereto a shiftingbottom plate 17, which coujointly acts with the bottom 15 of the section1 to serve as an extension of the bottom 16 of the section 2 or as anintermediate partition between the opposite portions of the draper 12,which move therearound. The movement of the draper 12 is regular, andthat portion thereof which travels above the bottom 15 and 16 and theplate 17 is closer to the latter parts to prevent too great sagging ordepression of said portion of the draper and also insure a close feed ofthe grain to parts which will be presently set forth.

The opposite sides 18 of the section 1, adjacent their rear ends, areformed with longitudinal slots 19, having rear lower bearing-recesses 20to receive the opposite extremities of the shaft 8 and to hold the shaftdown in the recesses. When the parts are arranged in operative relation,pivoted arms 21 are employed and connected to the said sides 18 by pins22, having eyes 23. On the rear ends of the arms 21 bearing-caps 24 aresecured and formed with upwardly projecting curved bearing-seats 25, thelower faces of the said caps having friction-clasps 26, secured at oneend thereto. 1 The said keepers are preferably construeted in the formof plate-springs, having their inner ends attached to corresponding endsof the caps 24 and the outer ends extended to provideoperating-terminals 27. That part of each clasp which extends acrossthe-bearing seats 25 is similarly struck n p, as at 28, and stands clearof thicsaid seat,

- so asito afford'sufiicient yielding movement to establish a resilientfasteningto hold the said arms 21 down in locked position againstaccidental disengagement and with suflicient resistance to overcomesuch-tendency due to the operation of the shaftS. The caps also have ayielding pressure on the oppositeportions of the shaft 8 through themedium of the clasps, and when the arms 21 are down in looking positionthey cover the slots 19 and prevent the passage of loosegrain'outwardl'y therefrom. By having the shaft Sadjustable and movablein the slots 19 the draper 12 can beslacke'ned and the section 1permit-ted to be thrown up over the section 2 without injury to saiddraper. When'the shafts is moved inwardly in t-heislots 19,.the-Lplate17 slides over the upper outer'portion of the bottom 15, and inreleasing the said shaft for this adjustment the clasps 26arefdisconnected by releasing them from frictional pressure and the arms21 thrown'up, as clearly shown by Fig. 4, to. uncover thev slots 19. Theimproved device can ,by'the means specifi'edbe reduced to compact formin a convenient lar'band 30. The lower-edge of the guide 29 is locatedso far above the planeof movement of the teeth 14 of the draper. 12 asnot. to interfere with the opera'tion of the latter, and

at its outer end said guide centrally extends to an inclined feed boardor plate 31, which also has its lower edge elevated'to clear the draper12. Theinnerextremitiesof thesides 18 of the section 1 are widened, asat 32, the said increased dimension beginning from the point oflocationofthe band ,30 and extending-'to the outer end of the section 2.Ex-

tending transversely across the sectioul and having bearings at itsopposite ends in the widened extremities 32 of'the sides I8is'a" shaft33, located adjacent the band 30 and having fixed thereon at regulardistances apart a series of band-cutting disks 34, which are obliquelyarranged to effect a shear-cut and are held in regular relation byinterposed spacing-sleeves 35, fitted on the sa id'shaft.. One'eud ofthe shaft 33, is projected beyond;

theadjaceut side of the section 1 and has a band wheel orpulley 36,keyed or otherwise fastened thereon and surrounded by a'belt 37,runningfrom a band wheel or pulley 38, fast on theprojected end of a shaft 39,having'bearing i'n'the upper outer portions o'f'the,

opposite sides 40' of the section 2. I At the inner portions of the saidsides of the section 2, in parallel relation to the shaft 39, a shaft 41has bearing, and on both shafts 39 and 41 7c sprocket-wheels 42are'keyed and surrounded by chain belts connected to an upper draper orfeeding-apron 43, also having cross-slats 44 at-regular-intervals,withteeth 45, curved in the direction of movement of the said draper thatpoi-flop 'of the-draper-43 which moves 8o thereover, longitudinal guards46 are secured to the inner faces of the sides 40 of the sec-v tion 2 topermit the chain belts or other devices connected to the draper 43 to beguided and sustained in 'a substantially horizontal plane.

The shaft 41 is extended outwardlyfrom the side of the section 2oppositeto'that from which the shaft 39 is projected and thereon issecured a cone or double pulley 47, having an outer enlargedband-engaging portion and an inner smaller band-face. The shaft 9 isextended'a't both ends beyond the opposite sides ofthe section 2, andthe extended end thereof'nearest theextended end of the shaft 41 alsohas a cone ordouble pulley 48' thereon, with two belt-faces. the pulley48 is double the diameter of the similar part of the pulley 47, and asimilar proportioncxists'between the inner'parts of said pulleys, thelarger dimensions being in the pulley 48. On the opposite extendedend ofthe shaft 9 is a pulley 49, surrounded by a belt 50, running 'fromlhedriven device 51 on the-thresher to'which the improveddeviee 1 5 isapplied. Friction mechanism 52', which will be more fullyhereinafter setforth, is supported adjacent the-pulley 49 and vpartiallylocated on theshaft 9. ,A frame 53 surrounds the extended end of the shaft. 9, no

bearing the pulley 49,, and affords a bearing .for said shaft end. i Thefriction-mechanismoperat-ing devices are also connected to the frame 53,and the function of said devices is to slow 'up'cr slacken the speed ofthe shaft.

9 and the draper 12. It will'also be observed that the-speed of rotationof the shaft 41 will be considerably in excess of that of the shaft 9,and consequently the draper 43-will travel.

"ifiu'chfaster than the draper 12, and to i'm5 12o par-t the motion ofthe pulley 48 to thep'ulley 47 a-crossed belt 54 is used. p

The shaft 9 is intended to be locatedat .a

suitable distance 'from the teeth of the cylinder of thethreshing-machineto which the device maybeapplied,andimmediately belowthesaid shaft is an inclined feed-chute 55, having a flat bottom adaptedto be closely arranged t-othe cylinder and concave of the thresher. Theinner-end of the section 2, 13b

which'isdisposed in the thresher adjacent the cylinder and'concave, isalso provided with a'hinged hood 56', that drops to aipointsuffici'ently low to shield'the working parts-in the The outer portionof section 2 and overcome any interference of the blast or otherair-currents in the thresher with the operation of the draper-s 12 and43. The hood 56 can be elevated at any time to expose the mechanism inthe adjacent part of the section 2 for the purpose of repair or othermanipulation. The outer reduced end of the chute 55 is open to serve asan airr feed and is held rigid by a cross-rod 57, secured in oppositehangers 58, and depending from opposite sides of the section 2 areskeleton brace-frames 59, having their inner vertical members, that maybe at times rested against the end timbers of the thresher. Rests 60project outwardly from the frame 59 and contact with the under oppositeportions of the inner end of the section 1 when the latter is inoperative position. -As a further means of holding the section 1 inhorizontal working position legs 61 are secured to the opposite sides18, about midway of the latter, and have a series of apertures 62therein to receive the ends of brace-rods 63, movably at tached to theeyes 23 of the pins 22. The function of these legs is well understood,and when the section 1 is folded overon the section 2, as shown by Fig.1, the braces 63 are disconnected from the legs 61, and the latter areadapted to be turned up against the opposite sides of said section 1through the medium of a pivotal connection, as at 64. Bindingstraps andother braces will be applied where necessary, and as a convenient meansof adjusting the shaft 8 the opposite ends are extended beyond the sides18 of the section 1.. The shaft 33 for the disk-cutters 34 is preferablysquare, and the openings through the said cutters and the sleeves 35 areof similar contour, with obvious advantages.

, The bound sheaves are thrown lengthwise on the feed board or plate 31,on opposite sides of the guide 29, and are caught by. the teeth 14 ofthe slats 13 on the draper 12 and by the movement of the latter fedunder the cutters 34, where the bands are severed and the loosened grainspread transversely on the 'said d raper and in this condition carriedunder the upper draper 43 and thence falls onto the bottom of the chute55, and subsequently between the cylinder and concave of the thresher.It will be observed that the arrangement of pulleys on the shafts 9 and11 is to effect a slower action or travel .of the low: draper 12 thanthe upper draper 43. It has been found that the best results are derivedby having the speed of movement of the lower draper only about one-halfas fast as the upper draper, and consequently when the grain is broughtunder the upper draper the more rapid movement of the latter willquickly feed off or separate the upper part of the sheaf from the lowerpart, and thereby ease the driving power and give the thresher,particularly the separator mechanism thereof, more time to efiectuallycarry on itswork with much less stress. This operation is facilitated bythe direction of the teeth 14, which do not feed with a direct pull onthe grain. The obliquity of the cutters 34 will also greatly assist inthe operation of the upper draper by dividing the sheaf as it passesthereunder. .By slowing the under draper and increasing the speed of theupper one the upper draper feeds with the same speed. but much lessstraw, as the under draper moves slower and holds the under part of thesheaf, as previouslyindicated.

The'friction mechanism 52 is composed of a longitudinally-disposed shortfixed shaft 64:, held in the opposite ends of the frame 53 close to theextended end of the shaft 9. On

said shaft 64 are loosely mounted friction-' rollers 65, which arelocated in front and rear of the extended end of the shaft9 andconnected to shoes 66 and 67. Movably attached to the shoe 66 is a link68, and in like manner to the shoe 67 a link 69 is secured. The link 69isshorter than the link 68, and the shoe 67 is in reverse position tothe shoe 66, and both links 68 and 69 are uiov ilolv connected to theshifting-lever 70, pivotal. 'upported on a fulcrum projection 71 fromthe end of the frame 53 adjacent the separator. The lower end of theshifting-lever 70 is provided with a grip or handle 72, and near thelatter is a dog 73, which is located near and in relative position to anarm 74, provided with a series of teeth 75. The pulley 49 is loose onthe extended end of the shaft 9 and is maintained in a certain outwardposition on the said shaft-extremity by a collar 76, which bears againstadjacent portions of the side of the frame of the band-cutting andfeeding attach ment. On the outer extremity of the extended end of theshaft 9 a frictiondisk 77 is fixed, and the friction-rollers-65 arelocated between the opposing faces of the said pulley 49 and disk 76,the contact of all of said parts being invariably maintained through themedium of an initial interval arrangement. Itwill be observed that theoperation of this friction-disk will be as follows:

Motion from the driving device 51 of the thresher or separator will betransmitted by the belt to the pulley 49 and from the latter through thefriction-rollers tothe disk 77 and through the latter to the shaft 9.This arrangement provides for the connection of all irregular movementsor fluctua- Lions of the driving element 51, and by shifting the rollers65 on the shaft 64: the speed may be varied to regulate the movement ofthe drapers, and to secure a more,positive action of these parts thebelt 54 is crossed. If the rollers 65 are simultaneously moved by thedevices connected thereto toward the conter of the pulleys 49 andfriction-disk 77, the

motion of the shaft 9 will be faster than when the said friction-rollersare nearer the peripheries of said pulley and friction-disk, and anadjustment can thus be obtained having a wide range and to accommodatevarious kinds of grains fed into the band-cutter and feeder. The shaft64 has an intermediate bend 78 to efiectively carry out the intendedresult.

Changes in the proportion, size, and the minor details ofconstruotion'can be resorted toywithout departing from the prineipleorsacrificing any of the advantages of the invention. i
